All lights turned off no power was going to the vehicle leaving us in the middle of the road while light turned green and then back to red twice we were just stopped with no electrical activity on the vehicle.

The auto idle stop is causing the van to not start up after stopping at red light or stop sign and it causes the van to completely go dead in middle of the road. You have to turn the van completely off, while people behind you are honking their horns at you, and then crank the van back up in order to get it to go again. All dash lights are on but the engine dies and will not start without having to shut the van off. This is very dangerous and frustrating for any vehicle to do this, but especially a 2025!!!! This happened today 10/12/2026 but has happened several times already with my family.

It was approximately 8:45 pm at night. I was sitting in my 2025 Honda Odyssey stopped at a red light with my foot on the brake. There were no other cars in front or behind me. It was a long light so the car engine stopped as it usually does due to its auto start-stop system to conserve gas (although electricity in the car remained on). However, when the light turned green, I took my foot off the brake and pressed the accelerator. At that moment, the entire car shut off unexpectedly, including all lights, electricity, etc. It appeared to be a "normal" shutdown as the "check rear passenger seats" indicator flashed before the car turned off (this is expected in a normal shutdown since we have a carseat in the rear seat). Fearful of being rear-ended at night, I quickly pressed the brake and hit the power button (the typical process for turning the car on). Thankfully this worked and the car restarted as normal. It took about 15 seconds for the car to power on such that I could shift the car into Drive and begin driving as normal. After that I proceeded to drive a further 20 minutes on highway + rural roads + stop lights and nothing else happened. - I do not know which component failed, but I suspect it was the starter as the car failed to restart after the auto-start stop system was engaged. - My safety was put at risk as the car was at a traffic light and turned off when I attempted to drive it when the light turned green. This meant my car was sitting in the dark with no lights on, at night, for about 15-30 seconds as I restarted it at a green light. I could have easily been rear ended at high speeds as people would likely not see my car at night trying to go through the green light. - The problem has not been reproduced by a dealer/service center. - It has not been inspected. - No messages prior to the failure.

When the vehicle comes to an idle stop and brake is released, the vehicle shuts off and does not kick back on. Only solution in the moment to get the engine to restart is trying to start the car repeatedly until it comes back on. Vehicle has been looked at for this issue but they were unable to replicate the issue. Engine light will sometimes come on when this occurs. Other times the charging system light comes on, as well having multiple warning lights coming on at once. Causes a safety issue when it’s not restarting while in traffic. Issues started a few months after purchase. Took it into the dealer and they determined the throttle body needed to be replaced.

Stopped in heavy traffic in a four lane highway. Auto start/stop shut the engine down as expected. Traffic ahead cleared. I took my foot off of the brake to step on the gas. The engine didn't start up, and the radio and all lights inside went blank. Traffic behind me approached at about 45 mph. and were swerving around to avoid hitting my dead vehicle from the rear. I pushed the start button. Nothing. Again. Nothing. Several times more with my foot on the brake, or off the brake. Nothing. I put it in park and kept trying the start button. Finally it started, the radio and dash display came on, and from then on it operated as usual. Scared the hell out of us. There was no warning that anything in the car was malfunctioning before this happened. Took it to the dealer. They looked it over, kept it overnight. Told me the next day that the battery can get drained too much if the air/cond is on max and the start/stop feature doesn't like that. They used a machine to drain the battery and recharge it and they tell me now that it should be good. I don't believe one has to be aware not to use the air on max while the start/stop is enabled. I'm afraid to drive the car now! Our lives were in danger.

Had the starter & battery replaced November 2025. It’s now June 2026 and it still is having trouble starting. It will sometimes not start and then just make a clicking noise and all the lights in the dash come on and air, but engine won’t well start. Then you take foot off break, then turn it off and try again it will start. The dealership ran tests and said everything was fine. When we first had this problem the car would stall out and shut off in traffic.

Vehicle stalled and shut down in traffic after the Auto Idle Stop function engaged at a red light turning the vehicle off and attempting to turn back on. All warning lights flashed. Vehicle would not turn on until after multiple attempts pressing ignition. This has happened multiple (3-4) times over a few months period. Honda dealership was unable to recreate incident but did identify difficulty with engine starting (i.e. slow crank) when manually turning on ignition; however, diagnostics found no issues.
